The current system of lifetime tenures for judges does not necessarily exemplify "We the people" because it can be argued that the system allows unelected officials to hold significant power for extended periods of time. The idea of "We the people" suggests that the people should have a say in who holds power and for how long, and the lifetime tenure system can be seen as contradicting that idea.
Whether or not justice should have lifetime tenures is a matter of debate. The lifetime tenure system was established as a way to protect judges from political pressure and to ensure judicial independence. However, some argue that lifetime tenures can lead to complacency, and that judges should be subject to periodic review or reappointment to ensure that they remain accountable to the people. Ultimately, the question of whether or not justice should have lifetime tenures depends on one's perspective on the role of the judiciary and the balance of power between the different branches of government.
